Rhode Island General Laws Title 6A. Uniform Commercial Code § 6A-2.1-222. Effect of tax increase on lease payments

(a) No lease relating to residential real estate shall contain a provision which obligates a lessee to make payments to the lessor on account of an increased real estate tax levied during the term of the lease, unless such provision expressly sets forth:

(b) If the exact percentage of any such increased tax contained in such a provision is found to exceed that proportion of such increased tax as the lessee's unit bears to the whole of the real estate so taxed, then the lessor shall return to the lessee that amount of the tax payment collected from the lessee which exceeded the lessee's proportionate share of the increased tax, plus interest calculated at the rate of five percent (5%) per year from the date of collection.

(c) Nothing in this section shall apply to existing leases but shall be included in all new leases.
